I study Mandarin since 2015 completely on my own, and I’m a subscriber since 2016. I have just reactivated my account after several months of inactivity. My vaguely defined goal for the next year is to increase the richness and complexity of my Mandarin. In those few days, since I’m again a subscriber, I have discovered many great old lessons (I mean really old, like 10 years old). I have studied a few and I have numerous questions. Where is the right place in the Forum to ask a linguistic question relevant to an old class? I don’t think the discussion part of those classes is active now.
